SPEIFICATION forming part of Letters Patent No. 367,849, dated August 9, 1857.

`Application [lod Derembcr G, 1856. Serial N|\.Q20,79. (Nomodel.)

complete specification, reference being had tol the accompanying drawings, and to the figures and letters marked thereon, forming a part of the said specification.

Myinvention relates to miter-boxes adapted for use with an ordinary croSscut-saw, and in which the miter-angle is adjustableat the will of the operator; and it consists of the devices and combinations herein. described and shown.

Referring to the drawings, Figure 1 is an elevation of one of the slotted saw-guides. Fig. 2 is a perspective view of the sliding block and spindle to which it is attached. Fig. 8 is aview of the block and spindle which support the stationary slotted saw-guide. Fig. 4 isa vertical section on one of the saw-'guides passing through its slot. Fig. 5 is a view of the miter-box complete. Fig. 6 is a vertical section of a saw-guide similar to that in Fig. 4, showing a modification in the mannerof fastening the saw-guide to the guide-bars.

A is the base ofthe miter-box, into which are laid three strips of hard wood, a, a', and a2, radiating from the center of the rear stationary saw-guide, B, and inclining forty-five degrees, ninety degrees, and one hundred and thirtyiive degrees, respectively, to the line of the back of the box C. l l

B, B', B2,.and B3 are the upright slotted sawguides, to be described hereinafter. The sawguides B and B2 are stationary, and the line connecting their centers is perpendicular to the line of the back of C of the miter-box.

To the front of the base A are attached the/ guidebars D and D', whichare separated from each other at each end by the blocks D2 D2.

Each of the upright saw-guidesV consists of an' and bz may be iliade to approach or recede from each other, thus regulating the width of the slot which receives and guides the saw.

space between the bars D and D', and a clamping-screw, b7, by which it may be clamped in any position upon the bars D and D.

The yblock b4 has a tongue, b5, which {it-s into the The saw-guide is provided with In Fig. 3 is shown the stationary block 118,

which supports the Saw-guide B, and screwed to the back of the base A.

In Fig. 6 is shown a modification of my device for attaching the saw-guides to the guidef bars D and D.

I provide the frame b'with a spindle, bm, which tits between the bars D vand D', 'and is screw-threaded at its lower end to engage with aclaxnpingnut, b. Between the clampingvnut and the bottom of the bals D and D5, I place a washer, bu.

By loosening the clampingnut b13 the sawguide may/be made to slide along the bars D and D or turn on the spindle'b12 as an axis.

The miter-box is operated as follows: The strip whose end is to be mitered is laid upon the base A and rml y held against the back C.

flfit is desired to cut the strip oft' squarely,

the stationary slotted saw-guides B and B2 are revolved on the spindles b b, respectively, so that their slotslie in the same plane, and are fastenedv in that position by tightening the clamping-screws b3 b3. The saw is then inser-ted into the guiding-slots of the saw-guides B and Bl and the piece Sawed off. It' the piece is to be niitered, one ot' the Saw-guides lB or B3 is moved along the guide-bars D and D until the angle between its Vcenter and the center of the saw-guide B and the line of the back'C is equal to the desired miter-angle, and fastened in that position by means of a clamping-Screw, bl. The saw-guides B and B or B3 are then turned on their spindles b b, respectively, so that their gnidingslots lie in the IOO same plane, and are fastened as before. rlhe saw is then inserted in the Slots and the piece sawcd off.

3y the use of the device shown in Fig. G the saw-guide B or may be secured in any position on the guide-bars D and D and its slot placed and held at the proper angle in one and bliesame operation by the elampi n g-n ut bl.

That I claim is i.. A miller-box having a vertical revolving saw-guide consisting o( an uprightslotted post havingin its base a socket and a base-block provided with an upright spindle, in combination with horizontal stationary guide-bars, whereby the Saw-guide is placed at any angle ab any point on Said guide-bars, substantially as described.

2. A lniter-box consisting of the base A, provided with two vertical saw-guides, B B2, horizonfnl guide-bars D D', and Lwo sliding vertical revolving` saw-guides, B' B, all arranged and operated substantially as described.

3. Arevolvinfm` vertical saw-guide having,` in its base a socket and a clamping-screw, in combination with a block which is provided with au upright grooved spindle, substantially as described.

4. A miter-box provided with horizontal guide-bars D'D, a block, b', provided with a tongue7 b, a clamping-screw, If, and an uprightl grooved Spindle, b, in combination with a revolving vertical saw-guide provided with a clamping-screw, If, substantially as described.

In witness whereof I have hereunto Sei; my hand.
